So I got the basic layout of my level done, time to go test it. After selecting load custom level and selecting the file, I just get stuck on my loading screen (The one with the arrows).

My level currently consists of these things:
All the NPC vehicle stuff
2 vehicle paths
plants, cars, buildings, billboards, and a enlarged overpass obstacle
There are currently 218 objects in all.

And a quick note:
I loaded up the example level frogger and copied and pasted a bus lane and removed everything else and started to build from there.
